Query not functioning

[Flybersite]

I've been looking for hours now what could be wrong but I don't really get what's wrong with the following query

$query = mysqli_query($GLOBALS['db_conn'],'SELECT config_value FROM '.get_config_value('database_prefix').'config'.' WHERE config_name = '.$config_name);

Does anybody see what's wrong with it?

I'm guessing you need quotes around the config_name value after the equals sign, assuming it is a non-numeric value.
